At 10, Keagan Bolibol invented the Problem Pad. Her invention has a dry-erase surface and fits in most three-ring binders, allowing students and professionals to work out difficult problems or equations without messing up their work.

While working on a difficult homework assignment, Keagan realized there had to be an easy way to keep her homework from turning out so messy. After talking with her father, she came up with the Problem Pad. Keagan won the 2007 Staples Invention Quest for her invention.
